Abstract
This study examines the relationship between meteorological parameters (temperature, humidity, wind speed) and the concentration of atmospheric pollutants (NO₂, CO, О3, SO2, PM2.5) in the city of Kostanay. Using correlation and regression analysis, statistical dependencies have been identified that determine the influence of weather conditions on the level of air pollution. It has been found that temperature positively correlates with ozone (O₃) and nitrogen oxide (NO), which is explained by their photochemical reactions. Humidity increases the concentration of CO and HS, but reduces the content of NO and o. Wind speed affects the dispersion of pollutants: with strong winds, the concentration of NO₂ and NO increases, but the level of SO2 and O₃ decreases. The data obtained helps to assess the environmental situation in the region and can be used to develop strategies for improving air quality and pollution monitoring.
